An automotive oscilloscope is a complex electronic device which stores and analyses the signal digitally and is capable of visually depicting regular changes in electrical activity. 

An automotive oscilloscope, earlier known and referred to as an oscillograph and unofficially referred to as a CRO, O-scope or scope (for cathode-ray oscilloscope), or DSO (for the more contemporary digital storage oscilloscope), is a kind of electronic test instrument designed to graphically display different types of signal voltages as a two-dimensional plot of one or more signals as a function of time frequently.

A dedicated automotive oscilloscope can also be referred to as motor-tester, engine analyzer or automotive lab scope. Browse through a wide selection of automotive oscilloscopes at Vetronix.
